I know it's of minimal consequence but I figured I'd give the religion some credence as well.

Bard: Bards seem to be able to be just about any religion except evil, although we've yet to have an evil race bard. This should hold true for the newly added races that aren't evil (Barb, Dwarf, Halfling) and I see no reason this should change, except for one nitpick: Dwarves are barred from Rallos Zek. Ever notice how all the other og warriors could follow Zek except Dwarves? Dwarves will KoS any followers of Zek, even their neighboring Elves and Gnomes. Thus Dwarves should probably not have this option lest you death loop upon creation. By contrast, Ogres would probably need to deliberately not have access to Brell as Dwarves are their sworn enemy.

Cleric: Usually every cleric has a faith and a necklace that has a clicky effect for their god.

Paladin/Shadow Knight: Also seem to have a religion. Usually a good/evil one specifically. For most races, the religions they follow are often available to the rest of the race's good/evil classes respectively on top of any other race's options.

Druids/Ranger: Also tend to have religion. Usually Karana or Tunare but the canon racepool is small and now we have an evil druid race (could maybe have one more?) I suppose a druid of Innoruuk defiling nature with hate or Bertox with sickness but most druids should otherwise follow the other two.

Iksars: Tend to overwrite all rules and devote only to Cazic Thule no matter the class.
